I got all my Clippard stuff from the UK dealer but Clippard have dealers world wide. All their parts are on their excellent site at www.clippard.com and they have all the pneumatic parts we could desire, prices very reasonable, inc air line.

The flow control needle valve is MNV1 and the check valve MCV1

I used the system EXACTLY as per BVM but with the addition of thie regulated nosegear and after the first flight the nose travel speed (up and down) was set, it is affected by air loads, and the gear operated flawlessly ever after.

The needle valves allow VERY precise control of travel speeds and as well as the F4 nose I use them to control the gear and speedbrake travel speeds on my big AW Hawks, again with excellent results and they just screw into the Jettronics valves on the exhaust side.

Strange you guys should raise the F4 this weekend , I have just finished repairing mine after some flameout damage (fail -safe finger trouble, the Pagasus HPES is flawless) like the real thing, it didnt glide too well with zero thrust and almost full tanks ! Engine running tho it is a fabulous machine !

Being modelled on the F4J I have installed a scale slotted tailplane, looks great and has no affect on handling.

PS Food for thought. Perhaps BVM could do with the F4 what they did with the F86, enlarge it by about 25 % for Olympus or JC 200 or even twin power to compete with machines such as those from Air World and Skygate and even C-ARF with the Mig 29 and A4 . With its really excellent scale profile, superb ground handling and quite docile flight characteristics (being basically a delta it has no nasty tendencies if you get the speed low). Could be the BVM flagship and with so many F4s having seen service around the world it would have very real appeal and probably be very succesful commercially for BVM. How about it Bob ?
